Osamu really is disappointed in the turn of things that he usually snap at his brother especially when both Suna and the blonde keeps clinging to each other.
He was obviously jealous.
For Suna... he couldn't turn to anyone except the blonde setter. He felt extremely close to him and encourage the setter to pursue his love for Sakusa. Suna noticed how irritable Osamu recently and he couldn't help but feel worried. It's been months since his breakup with Kita, and all he could do is avoid the guy.
Rintarō has always been hanging out with Atsumu more and more often. He realized how Osamu and Atsumu are complete opposite- though the younger is calmer in general, the spiker has also the tendencies to snap and act more like Atsumu.
At around this time, he noticed more things about Osamu that he hadn't noticed before even they became closed friends.
It was exactly the twin's birthday, and everyone on the team attended a small party for Atsumu and Osamu.
Everyone was there except Rintarō. He usually is absent when it comes to group activities like going out on a weekend to hangout, and birthday celebrations. He stopped extending practices with Akagi, and didn't even talk to anyone... well of course with one exception... Atsumu.
The party started with a blast as the third years prepared a song and dance presentation.
Kita would never do that in normal occasion of course... but surprisingly he did as requested by the third years.
Throughout the dance, Atsumu was frowning, and Osamu was beyond shock. He knew his brother so well, Atsumu is not blown away by how Kita is shaking his body, but hatred could be gleaned from those stares.
It wasn't the first time Atsumu ignore or gave the captain a disdained look. It started few months ago...
When the music stopped, Osamu's thought was put to a stop as well. Everyone started gathering up at the kitchen to indulge the food they brought and the foods the twins prepared.
Akagi and the others brought some vodka and wines. They all settled in the living room and talking about some stuffs. Atsumu was sitting on the couch opening some gifts from the team, while Osamu was busy cleaning the table top- removing the photo album which the other boys enjoyed looking at earlier.
Suddenly, Atsumu's phone rang, and the blonde stood.
"'xcuse me. I have to take this." he said going to the kitchen.
Osamu got a feeling that the caller is Suna, and for once, he wanted to know the truth between Atsumu and Rin's relationship, so he followed his brother to the kitchen.
He halted as he heard Atsumu's cheery voice.
"-you mean Suna! Yeah! Outside? Like right now? Wait... What surprise?!" Atsumu asked excitedly, smiling to himself.
If only it was on loud speaker, Osamu would know what the faux blonde is talking about or at least hear who's on the other line.
Atsumu dashed out of the kitchen through the backdoor, closing it behind him
"You okay, Osamu?" the spiker jolted, almost jumping from where he is standing.
"A..Akagi-san.. Ya almost gave me a heart attack, ya know! Don't appear all of a sudden like that!" Osamu said, rubbing his right palm to his own chest.
"Okay, Samu, sorry.. Wait, where's Atsumu?"
"I... I was about to follow 'im before ya decided to appear right next to me!" Osamu murmured disappointedly.
"Sorry about that-" the libero said chuckling a little.
"You're not suppose to leave your visitors alone in your house, Osamu." It was Kita who smiled at him as he approached the two.
"Even if you trust those people, you should be careful. Closer friends are the worst enemies." Kita continued. "Come on, let's go back to the living room." the captain said in which the two quickly obeyed.
Right, the person we trust the most is the same person who could bring us more pain.
Atsumu came back smiling widely. He got a reddish blush, and big gifts on his hand- he got two actually.
Everyone waved goodbye and the twins started cleaning up. Osamu didn't dare to ask or initiate talking to his brother until they finished cleaning.
Atsumu decided to take a bath first, and afterwards followed by Osamu.
"Samu... This is for ya!" Atsumu said handing one of the gifts earlier.
"T...Thanks." Osamu replied sitting beside his brother on the bed.
The younger started unwrapping the gift, curious.
"It's from Rin." Atsumu said, as the blonde also started to open the box.
So, it was Rin after all. Osamu scowled expression was so obvious, but the older twin didn't realize as he excitedly cut the tape off the top of the box.
"Say, Tsumu. Are ya and Rin dating or something?" Osamu asked mindlessly, not realizing he blurted it out loudly.
Atsumu's eyes widened in shock.
"Samu... Rin and I are-""I-... Nevermind! I'm goin' to bed!" Osamu replied leaving his gift there at Atsumu's bed.
Osamu didn't open the present and just decided to sleep the frustration he got inside his chest.
The younger woke up in the middle of the night, hearing Atsumu on the phone.
"I really love it, promise. I miss ya! I can't wait to see ya tomorrow on our date. I love you!" Atsumu said whispery before hanging up the call.
"Date ha?" Osamu mumbled to himself planning what he needs to do the next day- confronting his brother.
Closer friends are the worst enemies. Osamu hummed to himself before going back to slumber.
